I usually go ahead and update GCC because if there is a building problem 
with anything on the LFS/BLFS sites, there is a fix for it.

Now I see that GCC 4.9.1 has been released so there might have been some 
problems with the ".0" release.  So, since LFS is going to upgrade to 
that, I will try building Qt-4.8.6 with that and see if it works.  That 
will take a while even with a 4400+ processor.
